GAIA LEADER against its type
Built in 2011, it is 3 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 62,838 gross tonnage it is larger than 75% of the other 571 vehicle carriers with a recorded tonnage. It is one of 66 vehicle carriers here under the Japan flag, 9.3% of the 713 on the register. The same builder is recorded for 307 other vessels here, 55 of them vehicle carriers. The reported port of registry changed: SINGAPORE (2018–2019), then TOKYO (2023–2025).
Its 3,732 t of CO₂ for 2025 is 47% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 268.6 kg CO₂, 13% below the type median of 309.1 kg. It logged 1,027 hours at sea against a median of 1,639 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 5 years with reported emissions, the highest was 2025 (3,732 t) and the lowest 2024 (1,739 t). Its efficiency percentile within the type went from 7 in 2018 to 71 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 301 of 423 qualifying vehicle carriers by EEOI, at the 71st percentile. The dashed line is the type median, 51.7; this vessel reported 67.2.
EEOI divides emissions by transport work, which for this vessel and year was 55,496,728 tonne-miles over 13,891 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 3.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 114.6% and CO₂ per nautical mile fell 18.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
